“ Environmental Test Chambers – their value to industry” by airmid healthgroup limited briefly covers their general facility with four larger environmental test chambers and smaller chambers in their laboratories before focusing on their ASTM walk-in climate-controlled chamber located in the middle of the facility, with the labs surrounding the chambers.
The main environmental test chamber is double-skinned and sealed to control temperature, humidity, and air changes per hour while monitoring air particles and allergens in real-time. Air enters the chamber from the outside and is HEPA-filtered to remove particulates larger than 0.3 microns. The outgoing air is also HEPA-filtered.
A heating coil and humidifier enable computerized control of the chamber’s temperature and humidity.
The company performs tests for manufacturers of domestic environment goods such as appliances, flooring, and textiles. They primarily test for airborne particulates such as allergens, viruses, bacteria, and mold by taking samples from the chamber and sending them to their allergen or microbiology labs, with the latter testing for viruses, bacteria, and fungal spores.
The chamber has a positive pressure antechamber and multiple ports to draw samples, each drawing different particulates.
